08c56f3e2d element: ref-sink the correct pad template when replacing an existing one
templ is the new one that is being stored and that needs to be ref-sinked,
padtempl is the old one that just needs to be unreffed.

Fixes leaking the old template, and also makes sure that the new template is not
floating which can cause use-after-frees with bindings as they might wrongly
take ownership of a still floating template.

53c145a158 gstelement: protect async state changes against spurious wake ups
When a pipeline is pre-rolling, it waits for all sink elements to report
they have received a buffer before completing the transition to paused.
This async wait is done using a state condition variable. The way this
waits are currently implemented do not protect against spurious conditional
wake ups, which may happen due to external factors in the kernel.

This change implements the wait within a loop that iterates over the protected
variable to reinitiates the wait if the wakeup was spurious. More details in
the [GCond docs](https://docs.gtk.org/glib/struct.Cond.html).

15caeb4ac9 gstelement: fix deadlock in gst_element_add_pad() when >=PAUSED
gst_element_add_pad() is supposed to activate the pad if the element
state is >= PAUSED and the pad is not already active.

Unfortunately, before this patch, the activation was performed while the
element lock was still taken, which ended causing a deadlock in
gst_pad_start_task() as it attempted to post `stream-status` message in
the element, which also requires the element lock.

Elements could work around this bug by activating the pad manually
before adding it to the element.

This patch fixes the problem by performing pad activation only after the
element lock has been released.

339e5916c6 Build documentation for rust plugins
- Update the docker image we use, starting using the standard one adding
  `gtk4-doc` as required by rust plugins
- Update the plugins_doc_caches as required, some more plugins are built
  with the new image
- Install ninja from pip as the version from F31 is too old
- Avoid buildings all GSreamer plugins when building the doc as it takes
  time and resources for no good reason
- Stop linking to `GInstanceInitFunc` as it is not present in latest GLib
  documentation, leading to warnings in hotdoc.

d75a69ec95 gstinfo: remove the vasprintf fallback
We are always building our printf implementation, even when
GST_DEBUG is disabled, since we are exposing api (gst_print*)
that's dependant on our printf behavior.

We don't need to keep __gst_info_fallback_vasprintf around anymore.

Close #640

a3cbaa8209 element: Fix requesting of pads with string templates
Previously it was only possible to request them with the exact template
name, e.g. 'src_%s', but not with "instantiated" names that would match
this template, e.g.'src_foo_bar'.

This is now possible and a test was added for this, in addition to
fixing a previously invalid test.

fbf0cc2279 element: Add sanity check with a critical warning if a pad is requested for a pad template that is not installed on the element class
Various elements are assuming that the pointer matches a pad template
they know about, and also randomly created pad templates might be
missing some important information that is necessary to create a valid
pad.

For example, creating a new pad template for audiomixer's sinkpad
without providing the correct GType would cause audiomixer to create a
GstAggregatorPad. That will then later fail spectacularly because it
assumes that it got a GstAudioAggregatorPad.

Passing a pad template that does not belong to the element class in here
will easily lead to undefined behaviour.

b99ecc78ca Replace gst-i18n-*.h with gi18n-lib.h
GLib guarantees libintl is always present, using proxy-libintl as
last resort. There is no need to mock gettex API any more.

This fix static build on Windows because G_INTL_STATIC_COMPILATION must
be defined before including libintl.h, and glib does it for us as part
as including glib.h.

97c7fec8be gst: Add APIs to allow documentation for element to be skipped
Dynamically registered elements (hardware element in most cases)
may or may not be available on a system and properties may be different
per system.
This new API will make documentation skipping possible in programmable way.
